CVE-2018-12617 3 Canonical, Debian, Qemu 3 Ubuntu Linux, Debian Linux, Qemu 2020-11-19 5.0 MEDIUM 7.5 HIGH
qmp_guest_file_read in qga/commands-posix.c and qga/commands-win32.c in qemu-ga (aka QEMU Guest Agent) in QEMU 2.12.50 has an integer overflow causing a g_malloc0() call to trigger a segmentation fault when trying to allocate a large memory chunk. The vulnerability can be exploited by sending a crafted QMP command (including guest-file-read with a large count value) to the agent via the listening socket.
CVE-2020-16121 2 Canonical, Packagekit Project 2 Ubuntu Linux, Packagekit 2020-11-18 2.1 LOW 3.3 LOW
PackageKit provided detailed error messages to unprivileged callers that exposed information about file presence and mimetype of files that the user would be unable to determine on its own.
CVE-2016-6489 3 Canonical, Nettle Project, Redhat 6 Ubuntu Linux, Nettle, Enterprise Linux Desktop and 3 more 2020-11-16 5.0 MEDIUM 7.5 HIGH
The RSA and DSA decryption code in Nettle makes it easier for attackers to discover private keys via a cache side channel attack.
CVE-2016-6128 5 Canonical, Debian, Libgd and 2 more 5 Ubuntu Linux, Debian Linux, Libgd and 2 more 2020-11-16 5.0 MEDIUM 7.5 HIGH
The gdImageCropThreshold function in gd_crop.c in the GD Graphics Library (aka libgd) before 2.2.3, as used in PHP before 7.0.9, allows remote attackers to cause a denial of service (application crash) via an invalid color index.
CVE-2005-1260 4 Apple, Bzip, Canonical and 1 more 4 Mac Os X, Bzip2, Ubuntu Linux and 1 more 2020-11-13 5.0 MEDIUM N/A
bzip2 allows remote attackers to cause a denial of service (hard drive consumption) via a crafted bzip2 file that causes an infinite loop (a.k.a "decompression bomb").
CVE-2014-4508 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2020-11-12 4.7 MEDIUM N/A
arch/x86/kernel/entry_32.S in the Linux kernel through 3.15.1 on 32-bit x86 platforms, when syscall auditing is enabled and the sep CPU feature flag is set, allows local users to cause a denial of service (OOPS and system crash) via an invalid syscall number, as demonstrated by number 1000.
CVE-2017-13080 7 Canonical, Debian, Freebsd and 4 more 12 Ubuntu Linux, Debian Linux, Freebsd and 9 more 2020-11-10 2.9 LOW 5.3 MEDIUM
Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Group Temporal Key (GTK) during the group key handshake, allowing an attacker within radio range to replay frames from access points to clients.
CVE-2018-5802 4 Canonical, Debian, Libraw and 1 more 6 Ubuntu Linux, Debian Linux, Libraw and 3 more 2020-11-10 6.8 MEDIUM 8.8 HIGH
An error within the "kodak_radc_load_raw()" function (internal/dcraw_common.cpp) related to the "buf" variable in LibRaw versions prior to 0.18.7 can be exploited to cause an out-of-bounds read memory access and subsequently cause a crash.
CVE-2018-5813 2 Canonical, Libraw 2 Ubuntu Linux, Libraw 2020-11-10 7.1 HIGH 6.5 MEDIUM
An error within the "parse_minolta()" function (dcraw/dcraw.c) in LibRaw versions prior to 0.18.11 can be exploited to trigger an infinite loop via a specially crafted file.
CVE-2018-7858 4 Canonical, Opensuse, Qemu and 1 more 9 Ubuntu Linux, Leap, Qemu and 6 more 2020-11-10 2.1 LOW 5.5 MEDIUM
Quick Emulator (aka QEMU), when built with the Cirrus CLGD 54xx VGA Emulator support, allows local guest OS privileged users to cause a denial of service (out-of-bounds access and QEMU process crash) by leveraging incorrect region calculation when updating VGA display.
CVE-2019-19959 2 Canonical, Sqlite 2 Ubuntu Linux, Sqlite 2020-11-09 5.0 MEDIUM 7.5 HIGH
ext/misc/zipfile.c in SQLite 3.30.1 mishandles certain uses of INSERT INTO in situations involving embedded '\0' characters in filenames, leading to a memory-management error that can be detected by (for example) valgrind.
CVE-2010-2008 3 Canonical, Fedoraproject, Oracle 3 Ubuntu Linux, Fedora, Mysql 2020-11-09 3.5 LOW N/A
MySQL before 5.1.48 allows remote authenticated users with alter database privileges to cause a denial of service (server crash and database loss) via an ALTER DATABASE command with a #mysql50# string followed by a . (dot), .. (dot dot), ../ (dot dot slash) or similar sequence, and an UPGRADE DATA DIRECTORY NAME command, which causes MySQL to move certain directories to the server data directory.
CVE-2017-17499 3 Canonical, Debian, Imagemagick 3 Ubuntu Linux, Debian Linux, Imagemagick 2020-10-28 7.5 HIGH 9.8 CRITICAL
ImageMagick before 6.9.9-24 and 7.x before 7.0.7-12 has a use-after-free in Magick::Image::read in Magick++/lib/Image.cpp.
CVE-2017-14174 3 Canonical, Debian, Imagemagick 3 Ubuntu Linux, Debian Linux, Imagemagick 2020-10-23 7.1 HIGH 6.5 MEDIUM
In coders/psd.c in ImageMagick 7.0.7-0 Q16, a DoS in ReadPSDLayersInternal() due to lack of an EOF (End of File) check might cause huge CPU consumption. When a crafted PSD file, which claims a large "length" field in the header but does not contain sufficient backing data, is provided, the loop over "length" would consume huge CPU resources, since there is no EOF check inside the loop.
CVE-2018-15127 4 Canonical, Debian, Libvnc Project and 1 more 9 Ubuntu Linux, Debian Linux, Libvncserver and 6 more 2020-10-23 7.5 HIGH 9.8 CRITICAL

CVE-2018-20020 3 Canonical, Debian, Libvnc Project 3 Ubuntu Linux, Debian Linux, Libvncserver 2020-10-23 7.5 HIGH 9.8 CRITICAL
LibVNC before commit 7b1ef0ffc4815cab9a96c7278394152bdc89dc4d contains heap out-of-bound write vulnerability inside structure in VNC client code that can result remote code execution
CVE-2014-6052 4 Canonical, Debian, Libvncserver and 1 more 4 Ubuntu Linux, Debian Linux, Libvncserver and 1 more 2020-10-23 7.5 HIGH N/A
The HandleRFBServerMessage function in libvncclient/rfbproto.c in LibVNCServer 0.9.9 and earlier does not check certain malloc return values, which allows remote VNC servers to cause a denial of service (application crash) or possibly execute arbitrary code by specifying a large screen size in a (1) FramebufferUpdate, (2) ResizeFrameBuffer, or (3) PalmVNCReSizeFrameBuffer message.
CVE-2014-6054 3 Canonical, Debian, Libvncserver 3 Ubuntu Linux, Debian Linux, Libvncserver 2020-10-23 4.3 MEDIUM N/A
The rfbProcessClientNormalMessage function in libvncserver/rfbserver.c in LibVNCServer 0.9.9 and earlier allows remote attackers to cause a denial of service (divide-by-zero error and server crash) via a zero value in the scaling factor in a (1) PalmVNCSetScaleFactor or (2) SetScale message.
CVE-2018-7225 4 Canonical, Debian, Libvncserver Project and 1 more 9 Ubuntu Linux, Debian Linux, Libvncserver and 6 more 2020-10-23 7.5 HIGH 9.8 CRITICAL
An issue was discovered in LibVNCServer through 0.9.11. rfbProcessClientNormalMessage() in rfbserver.c does not sanitize msg.cct.length, leading to access to uninitialized and potentially sensitive data or possibly unspecified other impact (e.g., an integer overflow) via specially crafted VNC packets.
CVE-2014-6053 3 Canonical, Debian, Libvncserver 3 Ubuntu Linux, Debian Linux, Libvncserver 2020-10-23 5.0 MEDIUM N/A
The rfbProcessClientNormalMessage function in libvncserver/rfbserver.c in LibVNCServer 0.9.9 and earlier does not properly handle attempts to send a large amount of ClientCutText data, which allows remote attackers to cause a denial of service (memory consumption or daemon crash) via a crafted message that is processed by using a single unchecked malloc.
